SCOT-CLEAN ER YFOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 705,912, dated July 29, 1902.

Application filed December 3, 1901. Serial No. 84,515. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM EICHELBER- GER, a citizen of the United States, and a resident of Windber, in 'the county of Somerset and State of Pennsylvania, have invented a new and Improved Soot-Gleaner for Steam- Boilers, ot' which the following is a full, clear, and exact description.

My invention relates to improvements in soot-cleaners for steam-boilers; andthe object that I have in view is the provision of simple means for removing the deposits of carbon or soot on the interior surfaces of a boiler by the pressure of gaseous fluids, such as steam or air, and for conveying from the boiler the accumulated soot,which maybe discharged into an ash-pit or any other place.

With these ends in view the invention consists in the combination, construction, and arrangement of parts, which will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is anelevation looking at one side of a boiler-furnace and showing the series of tubes by dotted lines, the improved sootcleanerof my invention being applied in operative position to the furnace. Fig. 2 is a plan view of the soot-cleaner, showingthe boiler-furnace by dotted lines; and Fig. 3 is a detail section taken in the plane of the dotted lines 3 3 of Fig. 2.

In order that others skilled in the art may understand my invention, I have shown the soot-cleaner applied to a boiler of that class known as the Stirling,77 and in Fig. l a indicates the arch over the combustion-chamber; b, the front wallv of the furnace; c, the series of headers at the upper end of the furnace; d, the bottom header and mud-drum, and e f g are the groups of front, middle, and rear tubes, which are operatively connected with the headers in any usual way.

5 designates the feed-pipe,which is arranged outside of the boiler-furnace, preferably at one side thereof, and which has communication with a source of air-supply or with a steam-boiler, thus making provision for a supply of air under pressure or steam to the distributing-pipes of my improved soot-remover. Near one end of the'pipe 5 is provided a valve or stop-cock 6= and to this end of the pipe is Vattached a T-coupling 7, which serves to unite the branch pipe 8 to the feedpipe. The branch pipe S is disposed inl a vertical position, and atv one end it has a nipple 9, and to this nipple is coupled a horizontal distributing-pipe 10 by means of the packed joint l1, the said joint being of any suitable construction. The distributing-pipe l0 may be adjusted on its axis so as to turn through an arc of ninety degrees, and the packed joint 11 allows this adjustment of the pipe without leakage of the gaseous Huid. The pipe l0 passes through the side wall of the boiler-furnace, so that it will lie above the arch ct and adjacent to the front b of the furnace, and this pipe is provided with jetopenings or nipples l0, through which the fluid under pressure is discharged in jets.

^ The packed joint l1 and a handle 'or lever l2 for adjusting said pipe 10 are located outside of the boiler-furnace to enable the attendant to adjust said pipe 10 at any and all times. This distributing-pipe Yl0 lnay extend entirely across the boiler-'furnace parallel to the front thereof, and said pipe may be adjusted on its axis in order to direct the jets of steam or air against the front b or the group of circulating-pipes, (indicated at 6,) whereby the deposits of carbon may be blown from the front or the first group of pipes. The lower Vend of the branch pipe 8 has another distributing-pipe 13 coupled'thereto, said distributin g-pipe being arranged below the pipe l0,par allel therewith. This lower pipe lies directly over the arch ce, and it is furnished with jetopenings 14, that face in diiferent directions, so as to blow the jets of air or steam rearwardly over the 'arch and toward the lower portion of the first group of circulating-pipes e.

A T-coupling l5 is secured to the pipe 5 to one side of the valve 6, and from this coupling extends a vertical branch pipe 16, the same having a valve or cock 17. To the upper end of this branch pipe 16 is attached a third distributing-pipe 1S, the same passing through the side wall. of the boiler-furnace and extending across the furnace between the groups of circulating-pipes ef. This distributing-pipe 18 is provided with jet-openings which may face toward either or both groups of pipes e j', and said distributingpipe 18 may be adjusted on its axis, or it may occupy a stationary position on the branch pipe 16. Another T-coupling 19 is secured to the feed-pipe 5, and it has an upwardly-extending branch pipe 20, which is provided with a valve orstop-cock 21. From this branch pipe 2O extends a fourth distributing-pipe 22, the same passing through the side of the boiler-furnace Iand having an adjustable connection with the branch pipe by the packed joint This distributing-pipe 22 is provided with the handle or lever 24 for its convenient adjustment and with the jet nozzles or openings 25, whereby the pipe 22 is disposed between the second and third groups of pipes, and it may be adjusted on its axis for the nozzles 25 to face toward either group ot' circulating-pipesf or g.

The boiler-furnace may be provided in its sides with the usual cleaning-ont doors 7L.

From the foregoing description, taken in connection with the drawings, it will be seen that the series of distributing-pipes provide means for directing jets or streams of steam or air against the interior surfaces of aboilerfurnace, and the action of these jets blows the accumulations of soot or sediment from the various parts of the furnace, whereby the soot is blown toward the rear of the furnace and is likely to accumulate in the chamber back of the bridge-wall and below the muddrum d, said chamber being indicated at 1I. In this chamber is located a horizontal collecting-pipe 26, which is provided with a series of suction-nipples 27, certain of the nipples being located at the ends of the pipe, while other nipples are located at points intermediate of its length. (See Fig. 2.) At the middle of the collecting-pipe 26 is provided an injector-chamber 28, the same being shown in plan by Fig. 2 and in elevation by dotted lines in Fig. l. Into this injectorchamber enters the injector-nozzle 29, which is provided on the pipe 30, that is carried rearwardly through the boiler-furnace, and is attached to the feed-pipe 5 by the T-coupling 31, said pipe 30 having the valve or stop-cock 32. From the collecting-pipe 26 leads an offbearing conveyer-pipe 33, which is arranged in alinemcnt with the injector-chamber 28, and which pipe may lead to an ash-pit or any other place of discharge. The injection of the fluid, either steam or air, under pressure into the chamber 28 by the injector-nozzle 29 creates a suction through the pipe 26 and its nozzles 27 for the purpose of conveying the soot or sediment through the pipe 26 and into the pipe 33, the latter discharging the soot to a distant place.

Although I have s'hown and described a specific construction of mysediment-remover as applied to a particular type of boiler-furnace, it is evident that the invention may be used in connection with many other styles of boiler-furnaces and that the construction of the apparatus may be modified within wide limits in order to properly apply the same to such other styles of boiler-furnaces.

The improved apparatus may be usedwhen the fires are drawn and the furnace is at rest, or it may be employed when the furnace is in service. The use of the soot-remover during service of the furnace and the employment of air as the medium for blowing away the soot injects jets of air uniformly into the products of combustion, and thus supplies oxygen to the same, so as to insure the best results in the combustion of the fuel and to practically consume the carbon in the smoke.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A soot-remover for boiler-furnaces, comprising a series of horizontal distributingpipes disposed adjacent to the surfaces to be cleansed and within a boiler-furnace, each pipe provided with jet open-ings or nozzles, certain of. said pipes being adjustable axially and disposed between adjacent surfaces which it is desired to clean, and means for supplying gaseous fluid under pressure to said distributing-pipes. j

2. A soot-remover for boiler-furnaces, comprising a series o f horizontal distributingpipes disposed across a boiler-furnace and adjacent to the surface it is desired to clean, one or more of said pipes being adjustable axially and arranged to face toward two or more of the surfaces to be cleaned, a pipe for supplying gaseous fluid under pressure to all of the distributing-pipes, valved branch pipes between the adjustable pipes and said supply-pipe, and swiveled couplings for uniting the adjustable pipes to said valved branch pipes.

3. A soot-remover for boiler-furnaces, comprising a feed-pipe having branches, a horizontal distributing-pipe attached to one of the branches of the feed-pipe and disposed adjacent to a surface it is desired to clean, another distributing -pipe adapted to be adj usted on its axis and disposed parallel to the rst-named pipe, and a swiveled coupling between the adjustable distributing-pipe and the other branch of said feed-pipe.

4. A soot-remover for boiler-furnaces, comprising a valved feed-pipe, a branch pipe connected to the end of said feed-pipe, an adj ustable distributing-pipe coupled by a swiveled joint to one end of the branch pipe, another distributing-pipe made fast to the other end of said branch pipe, a series of valved branches extending from the feed-pipe,` and other distributing-pipes united to said valved branches and disposed between and adjacent to other surfaces of the boiler which it is desired to clean.

5. A soot-remover for boiler-furnaces, comprising a horizontal collecting-pipe adapted to be arranged in the lower portion of a boiler-furnace and provided with a series of suction-nipples, a conveying-pipe leading IOO IIO

from said collecting-pipe at a point between i jeetor also communicating with the feed-pipe certain nipples of the series, and an injector arranged to discharge fluid under pressure into said conveying-pipe.
